Fluoride fiber plasmonic sensor with multilayer variants of tungsten disulfide (WS2): Seeking enhanced figure-of-merit via thermo-optic tuning of radiation damping

AK Sharma, J Gupta - Optical Fiber Technology, 2019 - Elsevier
A multilayered fiber SPR sensor is studied with as many as five design variants governed by
different number (N varied from 1 to 5) of WS 2 monolayer for ethanol detection. The sensor
design variants are simulated and analyzed at 785 nm wavelength. The dynamic radiation
damping in terms of variable temperature and Ag layer thickness is enforced on the sensor
variants to lead to possible sensing performance enhancement. Further, an attempt is made
to more comprehensively evaluate the sensor's performance by including the power loss …
